Lennox 53W06 Expansion Valve Assembly

The Lennox 53W06 Expansion Valve Assembly plays anessential role in refrigeration circuits that limits the refrigerant flow thus ensuring efficient cooling and ultimate system performance. It works on the bases of proper control of the volume of refrigerant that is allowed to enter the evaporator coil. The valve is the point at which high pressure liquid refrigerant enters. This pressure drops when the flow passes through a small gap present in the valve. This rapid pressure drop leads to part of the liquid refrigerant turning into a cold low pressure gas and liquid mixture. This cold combination takes heat from the surrounding air to give the required cold effect.
